/// COMMON QUESTIONS · 1405 PROSPECT AVE

The short answers.

Is 1405 Prospect Ave rent controlled?

Outside LA RSO coverage on these records — most California multifamily over 15 years old falls under the AB 1482 statewide cap of 5% plus CPI, never more than 10% per year. This is an inference from public assessor records, not a determination — confirm the certificate of occupancy date with the LA Housing Department or ZIMAS before you rely on it for pricing or notices.

How many units does 1405 Prospect Ave have?

County records list 24 units at 1405 Prospect Ave, classified as 5+ units across 20,958 square feet of building area, averaging about 873 square feet per unit. Unit counts on the roll can lag permitted conversions and unpermitted additions in both directions.

When was 1405 Prospect Ave built?

The assessor roll gives a build year of 1987, which is after the October 1978 RSO cutoff. Age drives more than character here: it sets rent-cap exposure, seismic retrofit obligations, and what a lender will underwrite.

When did 1405 Prospect Ave last change hands?

The most recent transfer on the roll was recorded September 2019. Not every recorded transfer is a market sale — refinances, trust transfers, and family conveyances all appear in the same field, and those do not reset the assessed value.

What is 1405 Prospect Ave assessed at, and is that what it is worth?

The current assessed value is $4,470,360 ($1,456,849 land, $3,013,511 improvements). Assessed value is not market value. Under Proposition 13 it resets only on a change of ownership and then climbs about 2% a year, so a long-held building is often assessed far below what it would trade for.

How do I find out what 1405 Prospect Ave would sell for today?

Public records give you the frame — units, size, age, assessed value, when it last traded — but pricing needs in-place rents, expenses, and the condition of the units, none of which appear in county data. A broker valuation puts closed comps and a rent survey against the actual rent roll. Shaya Lowenstein does that free for LA multifamily owners, typically within 48 hours, with no obligation to list.
